Backwash Self Cleaning Filter

A backwash self-cleaning filter is a type of filtration system that employs a backwashing mechanism to automatically clean its filter media.

Here's how it typically works:

1. Filtration Stage: During normal operation, the fluid or gas flows through the filter media, trapping contaminants or particles on the surface.

2. Accumulation of Contaminants: Over time, as contaminants accumulate on the filter media, the flow rate may decrease, or the pressure drop across the filter may increase, indicating the need for cleaning.

3. Backwashing: When cleaning is required, the filtration process is temporarily reversed. A backwash cycle is initiated, where the flow direction is reversed or the pressure is increased. This causes the contaminated fluid or gas to flow backward through the filter media.

4. Contaminant Removal: The reverse flow dislodges and carries away the trapped contaminants from the filter media. The contaminants are then expelled from the system through a drain or discharge outlet.

5. Resuming Filtration: After the backwash cycle is complete and the contaminants are removed, the normal filtration process resumes, and the system is restored to its original operating conditions.

Backwash self-cleaning filters are commonly used in various industries and applications where continuous filtration is necessary without manual.
